[0008] (1) Outline of the Embodiment The following matters become clear from this specification and the accompanying drawings: The invention according to Embodiment 1 is a sheet-like contents container comprising: a container body having an outlet for dispensing the sheet-like contents and containing a laminate in which a plurality of sheet-like contents are stacked inside; and a lid that is rotatably attached to the container body about a pivot axis and moves in a closed state that closes the outlet and in an open direction that opens the outlet. The sheet-like contents container is provided with a biasing part that biases the lid. In the closed state, the biasing part biases the lid to move in the open direction. When the lid is opened beyond a predetermined angle, the lid is biased by the biasing part to prevent it from moving in the open direction. According to this embodiment, since the lid is biased from the closed state to the open state by the biasing part, the movement of the lid in the open direction can be assisted. Furthermore, when the lid is opened beyond a predetermined angle, the lid is biased by the biasing part to prevent it from moving in the open direction, so the swinging of the lid is suppressed and the lid can be easily stopped quickly at a desired stopping position.

[0009] In a preferred embodiment, the invention according to Embodiment 2 may have the following features in the invention according to Embodiment 1: The lid has a receiving portion that is biased by the biasing portion to prevent the lid from moving in the opening direction. One of the receiving portion and the biasing portion has a projection that protrudes toward the other of the lid and the container body and contacts the other when opened to a predetermined angle or more. In this embodiment, since the projection is biased, the entire member does not come into contact with the other, compared to a configuration in which the entire receiving portion is biased, and damage to the member can be suppressed. Furthermore, the degree of biasing can be changed by adjusting the shape and dimensions of the projection.

[0010] In a preferred embodiment, the invention according to Embodiment 3 may have the following features in the invention according to Embodiment 2: The protrusion is tapered toward the other side. According to this embodiment, the biasing force at the beginning of biasing can be made small and gradually increased, and the swinging of the lid can be suppressed by applying force in stages.

[0011] In a preferred embodiment, the invention according to Embodiment 4 may have the following features in the invention according to Embodiment 2 or Embodiment 3: The protrusions are provided in a plurality at intervals in the axial direction of the rotating shaft. According to this embodiment, by providing a plurality of protrusions spaced apart in the axial direction of the rotating shaft, biasing can be applied over a certain range extending in the axial direction, making it easier to apply force stably to the entire lid and suppressing the oscillation of the lid.

[0012] In a preferred embodiment, the invention according to Embodiment 5 may have the following features in the invention according to any of Embodiments 1 to 4: The lid has a receiving portion that is biased by the biasing portion to prevent the lid from moving in the opening direction. The rotating shaft is provided on one of the lid and the container body. The other of the lid and the container body is provided with a bearing portion that rotatably holds the rotating shaft. The contact points between the rotating shaft and the bearing portion are provided in pairs at intervals in the axial direction of the rotating shaft. The biasing portion and the receiving portion are arranged between the pair of contact points in the axial direction. According to this embodiment, the receiving portion can be biased by the biasing portion over a certain range extending in the axial direction of the rotating shaft, making it easier to apply force stably to the entire lid and suppressing the swaying of the lid.

[0013] In a preferred embodiment, the invention according to Embodiment 6 may have the following features in the invention according to any of Embodiments 1 to 5: The biasing portion is formed of an elastic material. According to this embodiment, since the biasing is performed by the elastic force of the elastic material, the force can be applied gradually. In addition, the impact when contacting the lid can be mitigated.

[0014] In a preferred embodiment, the invention according to Embodiment 7 may have the following features in the invention according to any of Embodiments 1 to 6: The biasing portion is folded with a first fold and a second fold along the axial direction as base points. The area of ​​the biasing portion folded by the first fold biases the lid in the opening direction. The area of ​​the biasing portion folded by the second fold biases the lid in the opening direction and also biases the lid to prevent it from moving in the opening direction when it is open beyond a predetermined angle. According to this embodiment, biasing to the open state and biasing to prevent movement can be achieved with a single biasing portion.

[0015] In a preferred embodiment, the invention according to Embodiment 8 may have the following features in the invention according to any of Embodiments 1 to 7: The predetermined angle is an angle greater than 60 degrees. If the lid is biased to suppress movement in the opening direction at an angle less than 60 degrees, the speed and momentum of the lid's movement in the opening direction will decrease, and the lid may not open to the desired angle. By biasing the lid to suppress movement in the opening direction at an angle greater than 60 degrees, it becomes easier to open the lid to the intended angle.

[0016] In a preferred embodiment, the invention according to embodiment 9 may have the following features in the invention according to any of embodiments 1 to 8: The angle at which the biasing portion begins to contact the lid may be a predetermined angle of 80 degrees or more and 90 degrees or less. By biasing the lid toward the closed state at an angle of 80 degrees or more and 90 degrees or less against the force with which the lid opens, it becomes easier to stop the lid near 90 degrees, and oscillation can be suppressed.

[0017] (2) Sheet-like contents container according to the embodiment The sheet-like contents container (hereinafter referred to as "container 1") according to the embodiment will be described below with reference to the drawings. In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of each dimension may differ from those of reality. Therefore, specific dimensions should be determined by referring to the following explanation. In addition, there may be parts where the relationships and ratios of dimensions differ between drawings.

[0018] Figure 2 is a perspective view of the container 1 according to the embodiment. The perspective views of Figure 1 and Figure 2 show a state viewed from the upper right side. Figure 1 shows a closed state in which the lid body 20 is closed, and Figure 2 shows an open state in which the lid body 20 is open. Figure 3 is an enlarged perspective view of the engaging portion between the lid body 20 in the open state and the container body 10, showing a state viewed from the front side. Figure 4 is an enlarged cross-sectional view of the engaging portion between the lid body and the container body in a cross section passing through the center in the lateral direction Y and along the longitudinal direction X and the vertical direction Z. Figure 4(A) shows the closed state, and Figures 4(B) and 4(C) show the open state. Figure 4(B) shows a state where the predetermined angle (α) is 60 degrees, and Figure 4(C) shows a state where the predetermined angle is 90 degrees.

[0019] The container 1 has an upper surface 1A, a lower surface 1B opposite to the upper surface 1A in the vertical direction Z, a left side surface 1C, a right side surface 1D opposite to the left side surface 1C in the lateral direction Y, a front surface 1E, and a back surface 1F opposite to the front surface 1E in the longitudinal direction X. The container 1 has the vertical direction Z that is the height direction, and the lateral direction Y and the longitudinal direction X that extend in the planar direction and are orthogonal to each other. The vertical direction Z is a direction extending vertically when the outlet 11 for taking out sheet-shaped contents is arranged facing upward. The upper side is the upper surface 1A (outlet 11) side, and the lower side is the lower surface 1B side. The longitudinal direction X and the lateral direction Y are directions orthogonal to the vertical direction Z, and extend horizontally when the outlet 11 is arranged facing upward. The longitudinal direction X is the depth direction in front view. The lateral direction Y is the left-right direction in front view, and may be the longitudinal direction of the stacked body. The vertical direction Z may be along the thickness direction of the sheet-shaped contents.

[0020] The container 1 accommodates a stacked body therein, and includes: a container main body 10 having an outlet 11 for sheet-shaped contents; and a lid body 20 rotatably attached to the container main body 10 around a rotation shaft 31, and movable between a closed state where the outlet 11 is closed and an opening direction where the outlet 11 is opened. The stacked body is formed by stacking a plurality of sheet-shaped contents. The sheet-shaped contents only need to be those constituted by sheets such as non-woven fabric, woven fabric, and paper, and examples thereof include dry sheets, wet sheets (wet wipes and face masks), and masks. The wet or dry sheet may be a sheet for the body such as hands and face, or may be a sheet for cleaning. The sheet-shaped content of the present embodiment is a wet wipe.

[0021] The stacked body may be accommodated in the container main body 10 in a stacked state, or may be accommodated in the container main body 10 in a state of being enclosed in a package. The package may be formed of, for example, a plastic film. A package opening may be formed in the package. The package opening serves as an outlet for the sheet-shaped contents. The package opening may overlap with the outlet 11 of the container main body 10 and be covered by the lid body 20.

[0022] The container main body 10 may include an upper portion 10A, a lower portion 10B, and a wall portion 12 extending in the vertical direction Z between the upper portion 10A and the lower portion 10B. The upper portion 10A constitutes an upper surface of the container, the lower portion 10B constitutes a lower surface 1B of the container 1, and the wall portion 12 constitutes a left side surface 1C, a right side surface 1D, a front surface 1E and a rear surface 1F of the container 1. The container main body 10 has an accommodation space for accommodating the stacked body. The accommodation space is a space surrounded by the upper portion 10A, the lower portion 10B, and the wall portion 12.

[0023] The upper portion 10A is provided with a lock mechanism 15 that locks the lid body 20 in the closed state, and an operation portion 16 that releases the locked state of the lock mechanism 15. The lock mechanism is a claw portion that engages with an engaging portion 23 of the lid body 20 in the closed state, and locks the lid body 20 in the closed state. The operation portion 16 is disposed on an upper surface 1A of the container 1 and interlocks with the lock mechanism 15. When a user presses the operation portion 16, the locked state between the lock mechanism 15 and the engaging portion 23 is released.

[0024] An outlet 11 is provided in the upper part 10A. The outlet 11 is an opening formed in the upper part 10A and communicates with the storage space. The upper part 10A has a recess formed therein in which the biasing part 35 and the lid 20, which will be described later, are housed. The recess is recessed towards the lower part 10B. The recess has a first recess 17 that houses the plate-shaped upright part 21 of the lid 20, and a second recess 18 located on one end X1 in the vertical direction X of the container body 10 and housing the biasing part 35 and the sliding contact part 22 of the lid 20. Here, one end X1 in the vertical direction X is the side of the rotation axis 31 and is the base point side for the rotational movement of the lid 20. The other end X2 in the vertical direction X is the side of the operating part 16 and is the leading end side for the rotational movement of the lid 20.

[0025] An outlet 11 is formed in the first recess 17. A main body rib 14 is formed on the upper side along the outer edge of the first recess 17. The main body rib 14 abuts against the lid rib 24 of the lid 20 when it is closed. The second recess 18 is located at one end X1 in the vertical direction X compared to the first recess 17. Upper wall portions 13 are provided on both sides of the second recess 18 in the lateral direction Y, projecting upward from the second recess 18. The upper wall portions 13 are provided in pairs, spaced apart in the lateral direction Y. A rotating shaft 31 is connected to each upper wall portion 13. The rotating shaft 31 extends inward from the upper wall portion 13 in the lateral direction Y and is rotatably held by the bearing portion 32 of the lid 20.

[0026] The rotating shaft 31 may be provided on one of the lid 20 and the container body 10, and the bearing portion 32 may be provided on the other of the lid 20 and the container body 10. In this embodiment, the rotating shaft 31 is provided on the container body 10, and the bearing portion 32 is provided on the lid 20. The rotating shaft 31 may be integrated with one of the container body 10 and the lid 20, or it may be a separate component connected to one of the container body 10 and the lid 20. In this embodiment, the rotating shaft 31 is formed integrally with the container body 10 and runs along the lateral direction Y at one end X1 in the vertical direction of the container body 1. The bearing portion 32 is formed integrally with the lid 20.

[0027] The lid 20 is positioned on the upper surface 1A of the container 1 and is configured to open and close the outlet 11 of the container body 10. The lid 20 is rotatably attached to the container body 10 about a pivot axis 31. In this embodiment, the lid 20 opens and closes with one end X1 in the vertical direction X as the pivot point. The lid 20 moves between a closed state, as shown in Figure 1, where the outlet 11 is closed, and an open state, as shown in Figure 2, where the outlet 11 is opened. In the closed state, the engaging portion 23 at the other end of the lid 20 in the vertical direction X engages with the locking mechanism 15 of the container body. When the user presses the operating portion 16 of the container body 10, the engagement between the locking mechanism 15 and the engaging portion 23 is released, and the lid 20 becomes movable in the opening direction. Here, the closed state is the state locked by the locking mechanism 15. Furthermore, the movement of the lid 20 in the opening direction is the movement in the direction in which the opening angle (a predetermined angle) of the lid 20 increases.

[0028] As shown in Figure 4, the lid 20 may have an upright portion 21 that stands upright on the upper side around the rotation axis 31 when opened from a closed state, and a sliding contact portion 22 that moves toward the biasing portion 35 side (the other end X2 in the vertical direction X) around the rotation axis 31 and slides against the biasing portion 35. The upright portion 21 may extend in the planar direction on the upper surface 1A. On the lower surface of the upright portion 21, a lid rib 24 is erected that contacts the main body rib 14 when the lid is closed. The sliding contact portion 22 is connected to one end of the upright portion 21 in the vertical direction X and may extend downward from the upright portion 21 when the lid is closed. The length of the sliding contact portion 22 in the lateral direction Y may be shorter than the length of the upright portion 21 in the lateral direction Y. The rotation axis 31 is inserted into both ends of the sliding contact portion 22 in the lateral direction Y, and bearing portions 32 that movably hold the rotation axis 31 are provided. The bearing portion 32 is a hole into which the rotating shaft 31 is inserted, and is located at both ends of the sliding contact portion 22 in the lateral direction Y. The sliding contact portion 22 and the bearing portion 32 are sandwiched between the rotating shaft 31 and the upper wall portion 13 in the lateral direction Y.

[0029] The container 1 of this embodiment is configured to quickly stop the lid 20 at a stop position while suppressing the swinging of the lid 20. Next, the configuration for quickly stopping the lid 20 at a stop position while suppressing the swinging of the lid 20 will be described in detail. The container 1 includes a biasing part 35 that biases the lid 20. The biasing part 35 engages with the container body 10 and the lid 20 respectively, and biases the lid 20 in different ways depending on the angle at which the lid 20 opens. In this embodiment, the biasing part 35 is formed separately from the container body 10 and the lid 20. However, in a modified example, the biasing part 35 may be formed integrally with the container body 10 or integrally with the lid 20.

[0030] The biasing portion 35 in this embodiment is composed of a plate-shaped elastic member having a predetermined width in the lateral direction Y. As shown in Figure 3, the biasing portion 35 is positioned in a region sandwiched between a pair of bearing portions 32 in the lateral direction Y. The length of the biasing portion 35 in the lateral direction Y is shorter than the distance between the pair of bearing portions 32. As shown in Figure 4, one end 351 of the biasing portion 35 is fixed to the lid 20, and the other end 352 of the biasing portion 35 is fixed to the container body 10. More specifically, the lid 20 has a first biasing fixing portion 29 that fixes one end 351 of the biasing portion 35. One end 351 of the biasing portion 35 is sandwiched between the lower surface of the upright portion 21 and the first biasing fixing portion 29 and fixed to the lid 20. The container body 10 has a second biasing fixing portion 19 that fixes the other end 352 of the biasing portion 35. The other end 352 of the biasing portion 35 is fixed within the second recess 18 of the container body 10 by the second biasing fixing portion 19.

[0031] Multiple folds are formed along the transverse direction Y between one end 351 and the other end 352 of the biasing portion 35. The folds are arranged from top to bottom as a first fold F1, a second fold F2, and a third fold F3. The first fold F1 and the third fold F3 are located on one end X1 in the vertical direction X of the biasing portion 35, and the second fold F2 is located on the other end X2 in the vertical direction X of the biasing portion 35. The first biasing fixing portion 29 fixes the area between the first fold F1 and one end 351 of the biasing portion 35 to the lid 20. The second biasing fixing portion 19 fixes the area between the third fold F3 and the other end 352 of the biasing portion 35 to the container body 10. The regions folded by the first fold F1, the second fold F2, and the third fold F3 overlap each other in the closed state, but in the open state, they unfold from each fold as a base point, and the folded regions separate from each other.

[0032] Figure 4(A) shows the closed state. When the lid moves from the closed state in the opening direction (the direction in which the angle of opening of the lid increases), the biasing part 35 biases the lid 20 to move in the opening direction. More specifically, the biasing part 35 deforms to unfold with the first fold F1, second fold F2, and third fold F3 as pivot points, thereby biasing the lid 20. When the lid is slightly unfolded from the closed state (for example, rotated by less than 10 degrees), the biasing part 35 deforms to unfold with the first fold F1 and third fold F3 as pivot points, and the lid 20 moves in the opening direction around the rotation axis 31. Figure 4(B) shows the lid open to a predetermined angle of about 60 degrees. The predetermined angle is the angle between the upper surface of the upright portion 21 in the closed state and the upper surface of the upright portion 21 in the open state, as viewed from the axial extension of the rotation axis 31. In the state shown in Figure 4(B), the biasing portion 35 unfolds from the third fold F3 as the starting point, and as the second fold F2 moves upward, it unfolds from the second fold F2 as the starting point, so that one end 351 of the biasing portion 35 biases the lower surface of the upright portion via the first fold F1.

[0033] In this embodiment, the biasing part 35 biases the lid 20 from a closed state to an open state, thereby assisting the movement of the lid 20 in the opening direction. In the housing 1 having a locking mechanism 15, the lid 20 is biased in the opening direction by the biasing part 35, but its movement is restricted by the locking mechanism 15. Therefore, when the locking mechanism 15 is released, the lid 20 is pressed by the biasing part 35 and rotates around the rotation axis 31, moving in the opening direction.

[0034] When the lid 20 is opened beyond a predetermined angle, the lid 20 is biased by the biasing portion 35 to prevent it from moving further open. More specifically, as shown in Figure 4(C), as the lid 20 rotates, the sliding contact portion 22 moves toward the biasing portion 35. When opened to the predetermined angle, the sliding contact portion 22 of the lid 20 contacts the vicinity of the third fold of the biasing portion 35 and is biased by the biasing portion 35. Furthermore, as the biasing portion 35 deforms to unfold with the second fold F2 as the pivot point, the sliding contact portion 22 is biased via the third fold F3. As a result, the sliding contact portion 22 is biased by the biasing portion 35, preventing further movement of the lid 20 in the opening direction. According to this embodiment, when the lid 20 is open beyond a predetermined angle, the lid 20 is biased by the biasing part 35 to prevent it from moving in the opening direction, thereby suppressing the swinging of the lid 20 and making it easier to quickly stop the lid 20 at a desired stopping position.

[0035] Furthermore, examples of biasing mechanisms to prevent the lid 20 from moving in the opening direction include the biasing part 35 contacting the lid 20 as it moves in the opening direction to reduce its speed of movement in that direction, and the biasing part 35 contacting the lid 20 as it moves in the opening direction to restrict its movement in that direction (preventing further movement). By providing the biasing part 35, it is possible to suppress the lid 20 from moving forcefully in the opening direction and to suppress the lid 20 from rotating beyond the stopping angle and swinging within a range that includes the stopping angle. In addition, by providing the biasing part 35, it is possible to suppress the lid from moving forcefully in the opening direction and exceeding the stopping angle, making it easier for the lid to stop at the intended stopping position.

[0036] The lid 20 may have a receiving portion that is biased by the biasing portion 35. The receiving portion is the part that the biasing portion 35 contacts. The receiving portion of this embodiment has a first receiving portion 27 that is biased toward the opening direction when closed, and a second receiving portion 28 that is biased so as to prevent the lid 20 from moving toward the opening direction when open. The second receiving portion 28 is biased by the biasing portion 35 so as to prevent the lid 20 from moving toward the opening direction, and thus constitutes the "receiving portion" of the present invention. The first receiving portion 27 is the part that one end 351 of the biasing portion 35 contacts, and is composed of a first biasing fixing portion 29 and the lower surface of the upright portion 21. The second receiving portion 28 is the part that the portion of the biasing portion 35 near the third fold F3 contacts, and is composed of the tip of the sliding contact portion 22.

[0037] As shown in Figure 3, the contact points between the rotating shaft 31 and the bearing portion 32 may be provided in pairs, spaced apart in the axial direction of the rotating shaft 31. The biasing portion 35 and the second receiving portion 28 may be positioned between the pair of contact points in the axial direction. According to this embodiment, the biasing portion 35 can bias the second receiving portion 28 over a certain range extending in the axial direction of the rotating shaft 31, making it easier to apply force stably to the entire cover 20 and suppressing the oscillation of the cover 20.

[0038] The biasing portion 35 may be formed of an elastic material. According to this embodiment, since the lid is biased by the elastic force of the elastic material, force can be applied to the lid 20 gradually. In addition, the impact when contacting the lid 20 can be mitigated. Silicone rubber can be an example of the elastic material constituting the biasing portion.

[0039] The biasing section 35 has the function of biasing the lid to move in the opening direction when it is closed, and the function of biasing the lid to prevent it from moving in the opening direction when it is open beyond a predetermined angle. The biasing section that realizes these two functions may be made up of separate members, or it may be made up of a single member as in this embodiment. The biasing section 35 that has two functions made up of a single member may be folded with a first fold F1 and a second fold F2 along the axial direction of the rotation axis 31 as the starting points. The area folded by the first fold F1 of the biasing section 35 biases the lid 20 in the opening direction, and the area folded by the second fold F2 of the biasing section may bias the lid 20 in the opening direction and prevent it from moving in the opening direction when it is open beyond a predetermined angle. According to this embodiment, biasing to the open state and biasing to prevent movement can be realized with a single biasing section 35.

[0040] The predetermined angle may be an angle greater than 60 degrees. That is, when the lid 20 is open 60 degrees or more from the closed state, the lid 20 may be biased by the biasing part 35 to prevent it from moving in the opening direction. If the lid 20 is biased to prevent it from moving in the opening direction at an angle of less than 60 degrees, the speed and momentum of the lid 20's movement in the opening direction will be reduced, and the lid 20 may not open to the desired angle. By biasing the lid 20 to prevent it from moving in the opening direction at an angle greater than 60 degrees, the lid 20 becomes easier to open to the intended angle.

[0041] The biasing portion 35 may begin to contact the lid 20, which is moving in the opening direction, when the biasing portion 35 is at a predetermined angle of 80 degrees or more and 90 degrees or less. That is, when the lid is opened less than 80 degrees from the closed state, the biasing portion 35 does not contact the second receiving portion 28, and when the lid 20 is opened 80 degrees or more and 90 degrees or less from the closed state, the biasing portion 35 may contact the second receiving portion 28. According to this embodiment, by biasing the lid 20 toward the closed state at an angle of 80 degrees or more and 90 degrees or less against the force with which the lid 20 is opening, it becomes easier to stop the lid 20 near 90 degrees, and oscillation can be suppressed.

[0042] (3) Container relating to the modified form Next, a modified housing will be described based on Figure 5. In the following description of the modified housing, the same reference numerals will be used for components similar to those in the above-described embodiment, and their explanation will be omitted. Figure 5 is a partially enlarged view of the housing 1 as seen from the bottom side with the lid open 90 degrees (as shown in Figure 4(C)), and shows an enlarged view of the sliding contact portion 22 and the biasing portion 35.

In the above-described embodiment, the second receiving portion 28, which is formed by the tip of the sliding contact portion 22, extends linearly in the lateral direction Y. The surface of the biasing portion 35 that contacts the second receiving portion 28 is a flat surface without any irregularities. Therefore, the second receiving portion 28 and the biasing portion 35 are in contact on a planar basis.

[0044] In the modified configuration, one of the second receiving portion 28 and the biasing portion 35 has a projection that protrudes toward the other of the lid 20 and the container body 10, and contacts the other when opened to a predetermined angle or more. In this configuration, since the projection is biased, the entire component does not come into contact with the other, compared to a configuration in which the entire second receiving portion 28 is biased, thus suppressing damage to the component. Furthermore, the degree of biasing can be changed by adjusting the shape and dimensions of the projection. In the following modified configuration, the projection is provided on the second receiving portion 28, but in other configurations, it may be provided on the biasing portion 35.

[0045] In the housing 1S of Modification 1, the protruding portion 41 is arranged in a strip shape at a position opposite the center of the biasing portion 35 in the lateral direction Y. According to this embodiment, since the protruding portion 41 extends over a certain range in the lateral direction Y, it is easy to bring them into contact even if there is a misalignment in the lateral direction Y between the biasing portion 35 and the protruding portion 41. The length of the protruding portion 41 in the lateral direction Y may be shorter than the length of the biasing portion 35 in the lateral direction Y.

[0046] In the modified example 2, the protrusion 42 in the housing 1T is tapered toward the other side. In the configuration in which the protrusion 42 is formed on the second receiving portion 28, the protrusion 42 is tapered toward the biasing portion 35. According to this embodiment, the biasing force at the start of biasing can be made small and gradually increased, and the swinging of the lid 20 can be suppressed by applying force in stages.

[0047] The protrusions 43 of the housing 1U in Modification 3 and 44 of the housing 1V in Modification 4 are provided in multiple locations spaced apart in the axial direction of the rotating shaft 31. According to this embodiment, by providing multiple protrusions spaced apart in the axial direction, biasing can be applied over a certain range extending in the axial direction, making it easier to apply force stably to the entire lid and suppressing the oscillation of the lid 20.

[0048] The spacing between the protrusions in the lateral direction Y is not limited. As shown in Modification 3, the protrusions 43 may be positioned opposite the regions located on both sides of the lateral direction, which are part of the region obtained by dividing the biasing portion 35 into three equal parts in the lateral direction Y. The elastic members constituting the biasing portion 35 are prone to deflection at their ends in the lateral direction Y. Therefore, by positioning the protrusions 43 opposite the regions located on both sides of the biasing portion 35 in the lateral direction Y, they become more susceptible to biasing force.

[0049] In the modified example 4, the protruding portion 44 of the housing 1V may be arranged in multiples in the lateral direction Y in a region that straddles the center of the biasing portion 35 in the lateral direction Y. According to this embodiment, since the protruding portion 44 extends over a certain range in the lateral direction, it is easy to bring them into contact with each other even if there is a misalignment in the lateral position between the biasing portion 35 and the protruding portion 44.

[0050] Although the present invention has been described in detail using the embodiments described above, it will be clear to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description herein is for illustrative purposes only and is not intended to be restrictive in any way to the present invention. [Explanation of symbols]
